Solvent-free photochemical formation of cubane-type Ru complexes from organometallic ionic liquids with cyanoborate anions†
Abstract
Coordination compounds, including cage compounds, are typically synthesized via solution reactions. Here, we report the solvent-free, quantitative conversion of organometallic ionic liquids (ILs) containing alkyltricyanoborate anions into solid tetraalkyl cubane-type tetranuclear Ru complexes upon UV irradiation. Furthermore, we elucidated the diverse packing structures of the octyl derivative.
